I were trying to study Deep Sleep example by uploading the example code from: GitHub - beegee-tokyo/RAK11310-RAK1906: WisBlock RAK11310 with RAK1906 Environment Sensor for LoRaWAN with AT Command Interface
After I follow the setup procedures as indicated in above link, I can see the code is successfully uploaded as shown below:
But when I tends to see any return message from the terminal, it show none.
When I switch back to Arduinio IDE and try to understand if the CPU is working, The serial monitor is freeze when I plug in the RAK11310 into my USB.
To elaborate what does it means by “freeze”, when I run serial monitor (or any thirds party terminal program), it just freeze and does not run, until I unplug the USB cable, and the terminal program will continue operating. I also need to mention that, when RAK11310 is plug into my USB port, the system can detect the port successfully.
So I try again upload an simple example code to RAK11310 using Arduino IDE and check again, and this time, RAK11310 no longer works. The code can be complied successfully but fail to upload to the CPU.
May I know if my RAK11310 is “bricked” and why? and is there anyway to “unbrick” the RAK11310 board?
Due to above incident, I have “lost” two RAK11310 boards, so I would like you to explain what is going on before I continue my board testing using PlatformIO again. Thanks.
